I need a way to Restore Columns Layout to Default in MultiCommander (perhaps with a Script or Custom Command perhaps?) This would be handy since I can bind it to a UDC hotkey as there's no Lock Layout option at present. This would be very useful for me!
P.S: Oh wow I used the "Customize Columns…" to set it to Auto-Load on "C:\" and "D:\" Paths and Subdirectories —it's working brilliantly now !!!

It's all here, hope it helps !
